. IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 176,233, dated April18, 1876; application filed I January 22, 1876.

To altwhom it may concern EGE, of Glen Rock, in the county of Nemaha andState of Nebraska, have invented a new and useful Improvement inSelf-Acting Seed- Droppers, of which the following is 'a specification:3

Figure 1 is a top view of our improved device, shown as applied to theframeof a seed- Fig. 2 is a vertical longitudinal sec- ;ion of the same,taken through the line a x,

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved device foroperating the dropping- .slide of a seed-planter by the advance of the'theframe, of a seed-planter. D are two parallel rings, which areconnected together and held intheir proper relative positions by- U-bars E, the ends of which are secured to the said rings. The innerringDis securely bolted to the inner side of one of the wheels A. To theinner side of the opposite parts of the rings D are secured inclinesF,as shown in Fig. 1. G is a bar that slides in keepers attached to theframe 0, and upon its end is formed, or to it is attached, a pin orfinger, g, which projects between the two rings D, so as to be struckalternately by the inclines F, to give the bar Gr a reciprocatingmovement. To the middle part of the sliding bar G is attached a pin, 9which passes through a longitudinal slot, h in-the end of a lever, H.The lever H is pivoted at its middle part to a cross-bar of the frameO,and has a short slot, 71?, formed in it to receive a pin, 12, attachedto the dropping-slide I of the planter, so that the said dropping-slideI may be operated by the advance of the machine. The slot h of the bar His made long, so that the end of the bar G may be thrown back-to throwits finger or pin 9 out of gear with the inclines F of the rings D. Thesliding bar Gris moved to throw it into and out of gear with theinclines F of the rings D by the lever J, the lower end of which isforked to receive the said sliding bar G, and which is pivoted tb a bar,K, attached to or connected with the frame 0 of the planter. The upperpart of the lever J passes across the edge of the curved bar L, the endsof which are attached to the frame 0, and in which are formed twonotches, l, to receive the lever J and lock the sliding bar G in placewhen-in gear and when out of gear. The lever J is held against thecatch-bar L by a spring, M, attached to the said lever J, and whichrests against a guardbar or keeper, N, attached to the said catchbar L.O are two wide bars, the outer ends of which are attached to the rim ofthe wheel A, directly in line with the inclines F. At a little distancebeyond the outer side of the wheel A, the bars 0 are bent inward, andhave holes formed in their ends to receive the outer end of the journalof the axle B. The bars 0 are designed to mark the line of the hills, sothat the seed may be planted in accurate check-row.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent--- The combination of the two parallel rings D,their connecting-bars E, and inclines F, the sliding bar Gr, providedwith the finger g and the pin 9 and the pivoted and slotted lever H,with the wheel A, the frame 0, and the dropping slide I of a planter,substantially as herein shown and described.
